Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486294, here are decompositions:
- 5 + 31486289 = 31486294
- 11 + 31486283 = 31486294
- 23 + 31486271 = 31486294
- 41 + 31486253 = 31486294
- 131 + 31486163 = 31486294
- 173 + 31486121 = 31486294
- 353 + 31485941 = 31486294
- 401 + 31485893 = 31486294
Showing the first eight; more decompositions exist.
